Pushing Bad Data- Google’s Latest Black Eye

Google stopped counting, or at the least publicly displaying, the quantity of pages it listed in September of 05, after a college–backyard “measuring contest” with rival Yahoo. That count numbertopped out roundeight billion pages earlier than it wasremoved from the homepage. information broke these daysthroughvarioussearch engine optimizationboards that Google had , over the past few weeks, broughtany other few billion pages to the index. this could sound like a reason for birthday celebration, however this “accomplishment” couldnow notreplicatewellat theseek engine that accomplished it. scraping google

What had the seonetworkbuzzingchanged intothe character of the fresh, new few billion pages. They had been blatant spam– containing Pay-per–click (%) ads, scraped content, and theywere, in lots ofcases, showing up nicelyin theseekeffects. They driven out far older, extraset upsites in doing so.

In amongavertinglocal vampire attacks, an enterprising local had a amazingconcept and ran with it, presumablyfar from the vampires… His ideawas to exploit how Google handled subdomains, and notonly a little bit, but in a massiveway.

The heart of the issue is that presently, Google treats subdomains a good deal the equalmanneras it treats fulldomain names– as precise entities. this meansit’llupload the homepage of a subdomain to the index and returnsooner or laterlater to do a “deep move slowly.” Deep crawls are without a doubt the spider following hyperlinks from the area‘s homepage deeper into the websitetill it revealsthe entirety or offers up and comesback later for greater.

briefly, a subdomain is a “1/3–degreearea.” you’ve gotpossiblyvisible them before, they looksomething like this: subdomain.domain.com. Wikipedia, for instance, makes use of them for languages; the English version is “en.wikipedia.org”, the Dutch version is “nl.wikipedia.org.” Subdomains are one mannerto organizemassivesites, rather thanmultiple directories or even separate domains altogether.

So, we’ve a type ofpage Google will index absolutely “no questions requested.” it is a marvelno one exploited this casesooner. a few commentators believe the motive for that may be this “quirk” changed intodelivered after the latest “hugeDaddy” update.

Spambots are sent out to position GoogleBot at theheady scentvia referral and remarkspam to tens of heaps of blogs roundthe sector. The spambots offer the hugesetup, and it would not take a lot to get the dominos to fall.
